LOOMl Specification forming part `Be it known that "I,BART0N H. JnNxs,

\ ofBridesburg, inthe countyof Philadelphia `and y State of.` Pennsylvania,have invented certain new and useful Improvements in i Looms, of "which,` the following is fa` full, clear, and exact description, reference being `had., tothe accompanying drawings, which Y make rari:` offithis: slSpatiorjl` y and in which; t. a a

Figure `l" representsman isometricalview of a portion of thegleftendzofthelay of theloom, and so much of the mechanism connected therewith` as" is necessary to show the application of my1improvements,there` 3 to `and `Fig. 2 represents an elevation fof.-` the rear side of the same showing theshuttle boxes lifted a shelf higher t-hanthcy appear In looms constructed] `as`iheretofore, the

` picker is very liable toobe broken by the` momentum with whichthe shuttle` strikes it.

With afvew to remedyfthis defectand also to prevent the thread` fromlbeing jarred olf the cop and'` (entangled, 1 I have @arranged a spring "lever alittle `beyond` the outer end.4 ofthe shuttle boxfor the picker to i y rest againstfso that `the momentum of the shuttle may be arrested a( gradually "and thus avoid the Sudden blow or percussion with which the shuttleimpinges upon the picker when held firmly and rigidly as in other looms.

rIhe mechanism for relieving or freeing the picker from the shuttle by a positive motion as heretofore patented by me, I have found to be although very useful,- not quite -as durablefand certain in its action as in In order to insure the prompt detachment bination with a lseriesof cams on the rod by which the shuttle boxes are lifted, so operates `1 as to free 1 the picker from the end ofthe shuttle` preparatory to moving the boxes.

of the picker from the end of the shuttle when the `rest is withdrawn, I combine the i `pickerby means of a string, link, `or other Wise witha spring lever, which constantly tends to draw the picker toward the outer end ofthe lay. l

Inthe accompanying drawing, a portion of the left end of the lay (A) is shown;

also a pieceof the sword (B) on which the end of the lay is supported; likewise a se-` ries of shifting shuttle boxes (C), and the lifting rod (D), by which-the shuttle boxes are raised and depressed; also the `picker (E) and the spindles or rods (F) on which itslides.

As mechanism for raising and lowering `shuttle boxes, the picker stick, and other ,mechanism `connected with the picking motioniare well known, and fully described in tiny former patents, I propose to omit all degscriptionof the same in the present applicaltion as superfluous except inso far as it may be necessary to refer to them in describing my present improvements.

On thefront end of the lay (A), a bracket (G) is secured 4which extends downward;

about the middle of this bracket the lower end of a lever (H) is secured by a pivot (a) and a spring I, extends from near the lower end of the bracket, and the spring thus arranged co-nstantly tends to turn the lever outward. The upper extremity of the lever is connected by a strap or cord (b) with the picker so that the latter shall constantly" be pulled outward by the same force which `tends tol turn the upper end of the lever (H) in the same direction.

A bracket (J) is attached to the under side of the lay, and extends downward. To the lower part of this bracket, an elbow or 'two arm lever (K) is held by a. pivot (o) on which the lever'turns. The upright and longest arm of thelever passes through a mortise or opening in the lay, and extends up` to a level with the top of the picker in order that the latter may rest against it, and thereby be limited in its outward mo'- tion. The horizontal arm of this lever (K) extends inward and rests upon the hori Zontal arm of a lever (L). The vertical arm (k) of the lever (K) is constantly drawn toward by a spring (M) which is connected to it, at one end, and at the other to the under side of the lay. Another bracket (N) projecting downward from the under side of the lay supports the lever (P) which is connected with it by a pivot (n).l The lower vertical arm of this lever, is provided with an obtuse wedge (d) projecting from its inner edge. This wedge enters notches (e) of a corresponding shape on the side of a sleeve (Q) on the lifting rod (D).

The sleeve (Q) is attached to the lifting rod, and has a longitudinal rib on it, and as many obtuse angled notches in it as there are shuttle boxes, and at the same distance apart respectively, as the shelves of the same. Under this arrangement, whenever the shuttle boxes are lifted by the rod (D) the movement of the sleeve up or down will force the wedge of the arm out of the notch in which it may be; at the commencement of this movement of the shuttle box, the wedge will be forced out of the notch, and so held by the rib between the notches, until the boX is changed to the required position to present another shuttle to the action of the picker, when the wedge will drop into another notch, being forced therein by the pressure of the spring (M) acting through the lever (K) upon the lever (P).

When the wedge (al) is forced out of the notches the lower vertical arm (p) of the lever (P) is moved outward; this raises the horizontal arm (P) and that in turnv raises the horizontal arm (715') of the lever (K) which moves the upper end of the arm (lc) outward, thus permitting the spring lever (H) to draw the picker outward far enough to disengage it from the outer end of the shuttle as shown by red lines in Fig. 2.

The lever or rest is so arranged as to receive the blow of the picker, and yield wit-hout disturbing the position or action of the other lever (P) which transmits motion from the notched rib t0 effect the separation of the picker from the shuttle at the proper time.

It will be observed that the tendency of the spring lever (H) is constantly to force the picker against its rest, while the tendency of the latter is to press against the picker, but the force with which the yielding rest presses inward must be so much greater than that which causes the picker to press outward, as to overcome it readily; otherwise the picker would not be returned after having been forced to its outermost position by the momentum of the shuttle.

It is obvious that the spring bar can be worked from other parts of the boX motion or can be worked by having a treadle in the loom. In that case the spring bar would be moved backward by every revolution of the cam shaft.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The yielding rest or support for the picker, arranged substantially as described, to break the sudden blow or concussion with which the shuttle impinges upon the picker, thereby preventing the lling of the cop from being jarred olf and entangled, and relieving the picker from danger of being broken.

2. I also claim separating or freeing the picker from the end of the shuttle by the same movement which shifts the shuttle boxes, operating through a combination of levers, cams, and springs, substantially as herein set forth, or through levers, cams or treadles worked from any part of the room.

In testimony whereof, I have hereunto subscribed my name.
